LINGUAL BAR.

Application filed November 1, 1926. Seriallto. 145,618.

My invention relates to improvements in lingual bars as used indentistry, which consist in the combinations, constructions andarrangements herein described and claimed.

An object of the present invention is to provide a lingual bar having aflexible joint intermediate its ends so that the saddles of the dentalplate or plates to whichthe ends of the lingual bar are secured may moveor settle in the mouth of the userv of the lingual bar as required toconform or fit snugly in the mouth of the user without injury to themouth of the user.

A further object of the invention is the provision of a lingual barwhich can be placed in applied position in the mouth of a patient easilyand which will remain in place in the mouth of the patient withoutcausing soreness of the gums of the patient.

Other objects and advantages of the invention will be apparent from thefollowing description considered in conjunction with the accompanyingdrawings, in which Figure 1 is a perspective view of the lingual barwith one end thereof attached to the saddle portion of a dental plate,and

Figure 2 is afragmentary sectional detail view of the joint between thesections of.

the improved lingual bar.

The improved lingual bar is made of any suit-able material and conformssubstantially in shape with the human aw, being substan tiallytl-shaped. The lingual bar that the invention provides maycomprise twocooperative sections 1 and 2, respectively, each of which is anapproximately onehalf part of the complete lingual bar. One of suchsections, as the section 1, is formed with a socket 3 in one end thereoffor the partial reception of a reduced ball head extension 4ion theadjacent end of the other section, a sufficient portion of the ball headt being received in the socket 3 to prevent disconnection of thesections from each other. The sections 1 and 2 thus will be connectedtogether for uni-' versal movement relatively to each other.

The outer end portions of the sections 1 and 2 are flattened asindicated at 5 and pro-' vide for serrations in the edges thereof, thusproducing teeth 6.

The outer end portions of the sections 1 and 2 of the lingual bar areadapted to'be imbedded or otherwise secured firmly to saddle members as7 of a partial denture plate or plates having teeth as at 8, thereon.

From the foregoing description of the various parts of the device theoperation thereof will be readily understood. Since the sections of thelingual bar are flexibly connected to each other, the saddles to whichthe ends of the lingual bar are secured may settle or move relatively toeach other in the mouth of a user of the lingual bar and thus may beadjusted as required to fit snugly and comfortably in the mouth of theuser, and such relative settling or movements of the saddles in the endsof the lingual bar may take place without any soreness of the mouth ofthe user being caused by pressure of the lingual bar thereagainst.Moreover, the universal joint between the sections of the lingual barpermits adjustment of the lingual bar quickly and easily in the mouth ofthe user and tends to obviate soreness of the gums or other portions ofthe mouth of the user when the lingual bar is in place.

Obviously the invention is susceptible of embodiment in forms other thanthat which is illustrated in the accompanying drawing,

and thereforeconsider as my own all such modifications and adaptationsas fairly fall within the scope of the appended claims.

' I claim 1. Alingual bar comprising a plurality o cooperative sect-ionsand a universal joint connecting adjacent sections to each other.

2. A lingual bar comprising two cooperative sections flexibly connectedto each other at their inner ends, and having their outer end portionsadapted to be attached to a dental plate,

3. A lingual bar comprising two coopera-.

tive sections, one of said sect-ions having asocket at its inner end andthe other section having a ball head extension at its inner endpartially received in said socket and cooperating with said socket toflexibly connect said sections together, the outer end portionof each ofsaid sections being" adapted to be attached to the saddle portion of adental plate.

r. A lingual bar comprising two longitudinally curved sectionsflexibly'connected together at their inner ends, the outer end portionof each of said sections being flattened and being provided with teethin the longitudinal edges of said flattened portion, whereby said outerend portion of the sections is adapted to be secured in place in thesaddle portion of a dental plate.
